AI coding tools make prototypes fast. Turning one into a reliable paid product still means rebuilding accounts, usage billing, credits, payments, fraud controls, attribution, lifecycle email, workers, admin tools, and deployment.
Velobase Harness packages that work into an MIT-licensed framework for AI SaaS builders. Start with a working product foundation, then spend your time on the part only you can build.
Harness helps you build and monetize the application. Velobase Cloud removes the infrastructure and deployment work.
Velobase Harness is an open-source AI SaaS boilerplate and application framework for developers who want to turn an AI prototype into a paid product. It combines the product infrastructure that most AI apps need after the demo stage: user accounts, billing, credits, payments, AI chat, workers, analytics, attribution, affiliate/referral systems, anti-abuse controls, admin tools, and deployment guidance.
Category: open-source AI SaaS framework, AI SaaS boilerplate, Next.js SaaS starter, usage-based billing starter, credit-based SaaS starter, monetization infrastructure for AI apps.
Best for: AI content tools, AI agent products, usage-based AI apps, credit-based SaaS products, indie AI products, internal AI tools that need production infrastructure, and teams adding monetization to an existing AI app.
Not for: teams looking for a no-code app builder, a hosted-only platform, or a finished vertical SaaS product. Harness gives you source code and production building blocks; you still build the product-specific workflow.
| If you are... | Start with... | What you get |
|---|---|---|
| An indie builder with an AI demo | Run Harness locally | Auth, billing, credits, payments, AI chat, admin, workers, analytics, and anti-abuse in one repo |
| A product team adding AI features | Read the framework guide | A production boundary for modules, services, events, queues, and third-party integrations |
| A builder who wants to ship without running infra | Try Velobase Launchpad | A prepared project, cloud resources, and an IDE prompt for your coding agent |
Once prerequisites are ready, you can run the full local stack with one command:
pnpm install && (test -f .env || cp .env.example .env) && pnpm docker:db:up && pnpm db:push && pnpm db:seed && pnpm dev:all
Open http://localhost:3000 and you have a working AI SaaS foundation: sign-in, billing data, credits, background workers, admin surfaces, and a place to build your product module.
Use open-source Harness when you want full code and infrastructure control. Use Velobase Cloud when you want the shortest path from repository to deployed paid product.
Accept subscriptions and usage-based payments, manage credits, meter AI usage, and give customers a billing dashboard from day one.
Connect purchases to acquisition channels with server-side attribution, Google Ads offline conversions, X pixel events, and PostHog analytics.
Run an affiliate program with a double-entry ledger, refund clawbacks, referral tracking, promo codes, and USDT cashout.
Reduce free-credit abuse with rate limits, Turnstile, disposable-email checks, signup signals, guest quotas, and credit clawbacks.
Use built-in auth, multi-LLM chat, background workers, lifecycle email, admin tools, Docker, Kubernetes, and GitOps guidance.
| You are... | Harness helps you... |
|---|---|
| An indie developer with an AI prototype | Add monetization and production infrastructure without starting over |
| A team already serving AI users | Add usage billing, attribution, affiliates, and anti-abuse controls |
| An AI-native builder using Codex, Claude Code, or Cursor | Give coding agents a documented production foundation to build on |
| Option | Best when you need... | Tradeoff |
|---|---|---|
| Blank Next.js or T3 app | Full control with minimal starting code | You still build billing, credits, workers, admin, attribution, and anti-abuse |
| ShipFast-style SaaS starter | A fast generic SaaS launch path | Often optimized for standard subscriptions, not AI usage and credit cost |
| No-code or low-code builder | Fast non-technical prototyping | Less source-level control and harder custom backend behavior |
| Velobase Harness | Open-source AI SaaS infrastructure with code access | You still implement the product-specific AI workflow |
| Velobase Cloud and Launchpad | Fastest managed path from idea to deployed AI SaaS | Less infrastructure ownership than a fully self-hosted setup |
Harness is MIT licensed and can be self-hosted. Velobase Cloud is the managed path for builders who want to skip provisioning and deployment work.
| Self-hosted Harness | Velobase Cloud | |
|---|---|---|
| Harness source code | Free and MIT licensed | Included |
| PostgreSQL, Redis, and storage | Configure and operate them yourself | Provisioned for you |
| Deployment | Configure Docker/Kubernetes and CI/CD | Git push to deploy |
| Infrastructure operations | Managed by your team | Managed by Velobase |
| Best for | Teams that want full infrastructure control | Builders th |
